2 Claims. (Cl. 93)

This application is a division of Serial No. 168,476, filed January 24, 1962, now Patent No. 3,176,320, granted April 6, 1965.

The present invention is concerned with a foldable and transformable piece of furniture of multiple functions, the particular construction of its components together with the folding of same and the additament of certain complementary pieces renders it susceptible to portability, to suspension, and to be converted into a table with or without an undershelf, a cradle, bed or sofa.

The object of the present invention is to provide a piece of furniture that can be folded for storage and can be transformed into various types of furniture as desired.

Further objects of the invention will be in part obvious and in part pointed out in the following detailed de-- scription of the accompanying drawings, in which;

FIG. 7 is a perspective view of a modification of the present device forming a childs bed;

FIG. 8 is an enlarged detail view of a spring connection;

FIG. 9 is a perspective view of a second modification of the present device forming a sofa.

FIG. 10 is a perspective view of a third modification of the present device as a sofa with back.

FIG, 11 is a perspective view of the present device forming the frame of a childs cot;

And FIG. 12 is an enlarged detailed cross-section view of a coupling for said childs cot.

FIGURE 1 shows one realization of the invention comprising a main framework of adequate material and dimensions, in which two similarly formed inverted U members 1 and 2 may be fitted with and sustain at the upper portions thereby, a frame consisting of four tubular curved members 3, 4, 5 and 6, and four straight tubular elements 7, 8, 9 and 10 into which the curved members are telescopically inserted and rigidly fixed by means of screws 11, said screws at the same time serving to rigidly fix said frame to the upper portions of the U members 1 and 2.

The aforementioned curved members 3, 4, 5, and 6 (see FIG. 2), are provided with holes 12 through which said screws 11 may pass and at the same time through the perforations 13 in the lugs 14 which can rotate on their cylindrical portions 15 within the plug bearing elements 16 which are solidly fixed to the extremities of the aforementioned straight tubular elements 7 and 8.

Said U members 1 and 2 are interconnected and joined to the frame by means of rods 17 which are firmly fixed to the lower leg portions of the U members by means of a ring 18 mounted on a leg and having a spring washer 19 with a bolt 11' extending through said washer ring and leg and a nut 20 in threaded engagement with said bolt and a second ring 21 fixedly connected and normal to ring 18 with bolt 11' extending through a spring washer 19, ring 21, rod 17 and also retained by a nut 20, FIG- URE 3. The other extremities of said rods are also fiattened out as in those extremities thereof shown in FIG. 3 and indicated by 17 in FIG. 1 and are joined to the upper frame by means of a screw 11 passing through the elements 9 and 10 and secured by a butterfly nut 22.

The extremities of the legs of the U elements 1 and 2 may be fitted with feet of adequate material screwed therein, or with rotary castors having a wheel 23, rotary support 23 and the threaded portion 24 for screwing into similarly threaded portions of the extremities of the U elements.

A flexible sacklike container 25 is conveniently suspended by straps 25a, FIG. 1, from the aforementioned upper frame which latter is provided with a handle 27 fixed to same by means of screws 11 while the bottom of the container 25 is provided with a rigid base board 26 and the cot or cradle is completed with a detachable rod 23 for suspending a veil 29.

In order to fold up the cot or its tubular structure, the rods 17 are separated from the upper frame by unscrewing the butterfly nuts 22 whereupon it will be possible to turn the U elements facilitated by the movable means described in connection with FIG. 2, by loosening the nuts 20 thus allowing the screws 11 shown in FIG. 3 to act as pivots for turning the rods 17, these latter may be folded back on to the U elements as soon as these have been placed into the position indicated in FIG. 4. As soon as the cot has been folded as indicated with the rigid base 26 of the container still in place, it may be suspended from existing adequate supports in trains, automobiles or the like, with the help of the detachable elements 22 which may also be used for the transport by hand of the equipment.

The transformation of the cot into a table is shown by FIG. 5, and is performed by the superimposition of the baseboard 26 on to said frame, to which it is fixed by means of screws 11. The table thus made may be transformed into a table with undershelf 26a as in FIG. 6, by

r the additament of supplementary feet 30 provided with threaded end portions similar to those of 24, FIG. 1, together with longitudinal tie bars 31 and cross supports 32, to which latter a board similar to 26 is fixed with screws 11, thus constituting the under-shelf.

FIGURE 7 shows the transformation of the cot into a childs cot, or the cradle into a cot, by coupling the U members 1 and 2 and the feet 30 to an angle section frame comprising two cross members 33 and two longitudinal members 34, all of which members are tied into the feet by means of tie-bars 33 and struts 34, said cross and longitudinal members being united to the upper portions of the U members by means of tie rods threaded at their lower extremities and screwed into the cross members, 35 into 33, while the upper extremities of said tie rods are united to a bridge piece which in turn is fixed by screws 11 to the upper portions of the said U members land 2.

In the childs cot now under consideration, railings are connected to a telescopic extension of the frame used in the basic cot, FIG. 1, in the table, or in the table with undershelf, integrated by the involved tubular elements 3, 4, 5, 6, 7 and 8, but without the tubes 9 and 10, and with the addition of two pairs of telescopic members 36 and 37 with member 36 having upwardly bent end portions, and threaded holes for the reception of the rods 38, while the latter are provided with end rings 39 that serve as guides for the straight end portions of the curved elements 3, 4, 5 and 6, whose other straight end portions are introduced into guides constituted by tubes that are screwed to the angle elements 34 at the lower extremities of said tubes while their upper extremities are solidly fixed to rings 41 which are fixed by screws 11 to the U elements 1 and 2.. The associated railings just described are fixed to the longitudinal members 34 by means of clamps screwed to the flats 36 in combination with looking butterfly nuts similar to those at 22, FIG. 1.

The frame formed by the cross and longitudinal members, 33 and 34 is provided at each of its corners with a tensor means for a mattress composed of strip elements 43 duly interlaced. Said tensors consist of stays 44, FIG. 8, to which pairs of threaded crank pins are adjustably fitted 45 parallel to each other by means of nuts 46, the other extremities of said crank pins being united to a stay 47 and to the strip elements 43 held by nuts 46. Castors may be fitted to this childs cot, similar to those shown at 23, FIG. 1.

The childs cot is converted into a bed, FIG. 9, by omitting railings and tubular guides 40, and by lengthening the frame support of the mattress by means of supplementary pieces 48 which are provided with feet 30 and stays 33'. Naturally, the mattress must also be lengthened by means of supplementary elements similar to 43.

Finally, the transformation of the bed into a sofa, FIG. 10, is effected by providing the former with a back, by shortening the bed railings and fitting them to one side of the mattress supporting frame, this side of the frame being provided at its extremities with the tubular guides 40 utilized in the childs cot, and at its centre with two more of such tubular guides fixed to the mentioned supplementary pieces 48 by means of supports 49, to which tubular guides the above mentioned shortened bed railings are fixed. The sofa is completed by means of the cross member 50 uniting the feet 30.

The frame used in the erection of the childs cot, FIG. 7 and the bed FIG. 9 may consist entirely of tubular elements, FIG. 11, in which there are two extreme end cross members 51 to which four tube elements 52 are fitted; two intermediate tube elements 53 for lengthening the bed, and two cross members 54 slidable on the tubes 52 by means of the T pieces 55 fixed solidly to members 54.

The union between the U elements 1 and 2, the tubes 52 and the cross members 51 is made by means of double rectangular T 56 screwed to the U elements 1 and 2 in the usual manner, and to which the end feet 30 are fitted. The tubes 53 are coupled to the central feet 30 by means of screwed pins 57 FIG. 12, for additional support at center of bed. The tubes 52 and the T pieces 56, are fixed together by means of screws 58, FIG. 12, while said tubes 52 are drilled for fixing to similarly drilled tubes 53 by means of through bolts 58.

The mattress is stretched between the slidable cross members 54 and held in tension by long screwed bolts 60 sustained by end cross members 51.

Having now particularly described and ascertained the nature of said invention and the manner in which it is to be performed, what I claim is:

1. A foldable and transformable piece of furniture comprising a pair of similar inverted rigid U-shaped members, a rectangular tubular frame consisting of two pairs of straight members with the members of each pair being of equal length and four symetrically curved tubular members with each end of each tubular member being telescopically inserted in one end of one of said straight members, one pair of said pairs of said straight members having each straight member thereof fixedly mounted on the base of one of said U-shaped members and pivotal about the curved members inserted therein, rods pivotally connected to the legs of said U-shaped members and each detachably connected to one of the other of said pairs of straight members and a rigid base detachably mounted on said straight members.

2. A foldable and transformably piece of furniture as claimed in claim 1 wherein the leg ends of said U- shaped members are threaded; a plurality of end feet have threaded engagement with said U-shaped member leg ends, there is a plurality of crossbars, each crossbar has end openings with each ofsaid end feet threaded ends extending through one of said crossbar end openings and said crossbars extend between the legs of said U-shaped members, and a second rigid member is detachably mounted on said crossbars providing an undershelf.
